Abstract

We report torque magnetometry results on single crystals of karpenkoite Co3(V2O7)(OH)2·2H2O, a model candidate for the kagome antiferromagnet. No field-induced phase transition is detected up to 45 T for B || c and B || a. Instead, the torque reveals a continuous spin reorientation toward saturation, most likely governed by a dominant Dzyaloshinskii–Moriya interaction.
